The word avionics is formed by combining the words aviation and electronics. Avionics is the application of electronics to the operation of aircraft, spacecraft, and missiles. Avionics technicians inspect, test, and repair the electronic components of aircraft communication, navigation, and flight control systems.
Using test equipment such as circuit analyzers and oscilloscopes, technicians test and replace sophisticated radar systems, transponders, and transceivers. They also test and maintain control equipment such as autopilots.
Avionics technicians work with engineers to install new electronics systems. The new equipment is tested and calibrated to specifications. Technicians adjust the frequency of communications systems by signaling ground stations and making adjustments until the desired frequency is reached. Once in service this equipment must be checked and readjusted regularly to maintain the correct frequency. Avionics technicians must complete and sign installation and maintenance documentation for every piece of equipment.
Some avionics technicians work with avionics engineers in developing new electronic systems and components for use in the aerospace industry. They may test new equipment and suggest design changes that ensure the equipment can withstand certain operating conditions.
Because many different kinds of electronic systems are used in aircraft today, avionics technicians usually specialize in areas including radio equipment and computerized guidance and flight control systems. In addition, new specialties are constantly opening up as new developments occur. Technicians are expected to keep up with new technological advances in their field. They do this by reading technical articles and attending seminars and training courses in new electronic applications in aviation.
Education and Training
Avionics technicians must have a high school diploma and complete a course of training at a technical institute or community college. Those who do not take an avionics course must obtain a solid background in the theory and practice of electronics. Other useful courses are geometry, calculus, and technical writing. Large aerospace companies and the armed services provide on the job training specific to their requirements. Avionics technicians are also required to obtain a restricted radio telephone operator's license.
Getting the Job
Your college's placement office should be able to provide you with information about entry level positions. You can also apply directly to aerospace companies and airlines. Some employment agencies specialize in placing technical staff and may be able to help you find a position.
Employment Outlook
Avionics technicians usually begin their careers as trainees, working under the supervision of experienced technicians. As they gain experience they test and repair avionics equipment independently. Some technicians advance by being made responsible for installing new equipment, others by moving into positions in research and development.
The employment outlook for avionics technicians is fair. The aerospace industry is closely tied to government spending and the economy, and government cutbacks in defense spending have slowed demand for avionics technicians.
Working Conditions
Avionics technicians generally work 40 hours a week. Because of the nature of the electronic equipment they work with, technicians work in very clean, in door conditions. This work may have to be done in the confined spaces of air craft cockpits. The work is very detailed and has to meet exacting standards. Technicians sometimes work in teams, cooperating with other technicians and engineers. They may have to prepare technical reports and make presentations.
Earnings and Benefits
Currently, entry level avionics technicians earn between $18,000 and $20,000 a year. Salaries for experienced technicians average around $30,000 a year, depending on the type of company or size of airline. Managers and supervisors earn $35,500 to $38,000 a year.
Benefits usually include paid holidays and vacations and health and pension plans. Technicians working for airlines may also receive free or greatly reduced fares when traveling.
